In very large distributed computer systems, there are significant problems when one considers decentralization of control amongst agents managing resources. Probably the most difficult is that agents must make good fast coordinated decisions based on uncertain and differing views of the global system state. Our thesis is that despite such problems, effective decentralized control systems can be built based on a set of seven design principles which we describe. We also apply these principles to...

Shared memory multiprocessors are considered among the easiest parallel computers to program. However, building shared memory machines with thousands of processors has proven difficult. Two main problems are the long latencies to shared memory and the large network bandwidth required to support the shared memory programming style. In this dissertation, we quantify the magnitude of these problems and evaluate multithreading and caching as mechanisms for solving them. Multithreading works by...

This thesis develops new methods for addressing the problem of software security bugs, shows that these methods scale to large commodity software, and lays the foundation for a service that makes automatic, effective security testing available at a modest cost per bug found. We make the following contributions * We introduce a new search algorithm for systematic test generation that is optimized for large applications with large input files and exhibiting long execution traces where the search...
